Description

[0002] In the field of sewage treatment, catalytic filter element usually refers to a filter element containing a specific catalyst, which is used to treat organic pollutants, harmful chemicals or heavy metals in sewage. The function of this catalytic filter element is to convert these harmful substances into harmless or easy-to-treat substances through catalytic reactions.

[0003] When the catalytic filter element is working, the suspended matter, microorganisms, heavy metal ions in the sewage and the chemical reaction of the filter element material produce sediments that will settle on the surface of the filter element. If it is not cleaned for a long time, the filter element will be clogged, thereby reducing the filtering efficiency of the filter element.

[0061] In order to make the purpose, scheme and advantages of the technical solution of the present application clearer, the technical solution of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present application. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0062] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] As described above, in the use of traditional catalytic filters, impurities contained in sewage can easily clog the filter element, requiring regular manual cleaning, which is time-consuming and labor-intensive. However, existing cleaning devices have complex structures, occupy a large filter bin space, and have poor cleaning effects.

[0064] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, an example embodiment of the present application provides a sewage treatment filter device, which includes: a filter bin, configured to define a cavity for temporary storage of sewage; a catalytic filter element, disposed in the filter bin and configured as a spiral structure; and a cleaning device, sleeved on the outer wall of the catalytic filter element; a driving device, connected to one end of the catalytic filter element, configured to drive the catalytic filter element to rotate around its own central axis; a limiting device, slidably connected to the cleaning device, configured to limit the moving direction of the cleaning device, so that when the catalytic filter element rotates, the cleaning device rotates and moves around the surface of the catalytic filter element, thereby automatically cleaning the surface of the catalytic filter element, extending the service life of the catalytic filter element, and improving the cleaning efficiency and cleaning effect.

[0065] The sewage treatment filtering device according to the embodiment of the present application is exemplarily described below with reference to the accompanying drawings. Figure 1 A schematic diagram of the structure of a filtering device according to an embodiment of the present application is shown. Figure 7 A schematic diagram of the structure of a catalytic filter element according to an embodiment of the present application is shown. Fig. 9 A front view of a filter cartridge according to an embodiment of the present application is shown. Fig.10 Show Figure 8 Cross-sectional view along the BB direction.

[0066] A sewage treatment filtering device comprises: a filter chamber 1, configured to limit a cavity for temporary storage of sewage; a catalytic filter element 2, disposed in the filter chamber 1 and configured as a spiral structure; and a cleaning device 3, sleeved on the outer wall of the catalytic filter element 2; a driving device 4, connected to one end of the catalytic filter element 2, configured to drive the catalytic filter element 2 to rotate around its own central axis; a limiting device 5, slidably connected to the cleaning device 3, configured to limit the moving direction of the cleaning device 3, so that when the catalytic filter element 2 rotates, the cleaning device 3 rotates and moves around the surface of the catalytic filter element 2.

[0067] During use, sewage continuously enters the filter chamber 1, and the sewage enters the filter element from the surface of the catalytic filter element 2, and the filtered water is output from the end of the filter element away from the driving device 4. When the filter device has worked for a certain period of time, the driving device 4 is started, and the spiral structure of the catalytic filter element 2 is driven by the driving device 4 to rotate around its own central axis. Since the cleaning device 3 is sleeved on the surface of the catalytic filter element 2 and one side is pulled by the limiting device 5, the cleaning device 3 moves on the surface of the catalytic filter element 2 and cleans it. At the same time, it can also reciprocate up and down along the limiting device 5 to clean the entire outer wall of the catalytic filter element 2. In daily filtration, the driving device 4 can be optionally used. It works continuously, and performs cleaning and maintenance while filtering sewage containing many impurities. For sewage containing few impurities, the driving device 4 can be started after an interval, and the cleaning frequency can be selected according to the actual usage. In addition, the spirally configured catalytic filter element 2 can not only be used alone, but also can be set in multiple groups in the filter bin 1. Compared with the traditional straight-cylinder filter element, the filter element with a spiral structure can increase the filtration area in the filter bin 1 with limited space. The cleaning device 3 is driven to work by the filter element with its own spiral structure, which can also reduce the space occupied by the cleaning device 3, improve the utilization efficiency of the space in the filter bin 1, and ensure the normal operation of the filter element while increasing the service life of the filter element.

[0068] Figure 1 A schematic structural diagram of a filtering device according to an embodiment of the present application is shown. Figure 4 A schematic diagram of a sealing plate structure according to an embodiment of the present application is shown.

[0069] The filter chamber 1 includes: a cylinder 11, in which the catalytic filter element 2 is arranged; a driving plate 12, which is rotatably arranged at one end of the cylinder 11, one side of which is connected to one end of the catalytic filter element 2, and the other side of which is connected to the driving device 4; and a sealing plate 13, which is rotatably arranged at the end of the cylinder 11 away from the driving plate 12, and one side of which is connected to the catalytic filter element 2; an inlet pipe 14, which is connected to the inner wall of the cylinder 11 and is configured to provide sewage into the cylinder 11; and an outlet pipe 15, which is arranged on a side of the sealing plate 13 away from the catalytic filter element 2 and is connected to one end of the catalytic filter element 2.

[0070] During use, the driving device 4 drives the driving plate 12 to rotate on the inner wall of the bottom end of the cylinder 11. When the driving plate 12 rotates, the catalytic filter element 2 on the surface is driven to rotate around its central axis. The catalytic filter element 2 is closed at one end close to the driving plate 12 and is eccentrically arranged with the driving plate 12. The other end passes through the sealing plate 13 and is connected to the outlet pipe 15. When the driving plate 12 rotates, the sealing plate 13 is driven by the catalytic filter element 2 to rotate on the inner walls at both ends of the cylinder 11. When the sewage enters the cylinder 11 from the water inlet pipe 14, the sewage enters the interior through the surface gap of the catalytic filter element 2 under pressure, and the catalytic material on the surface of the catalytic filter element 2 decomposes organic matter in the sewage, removes odor, reduces the concentration of pollutants, and improves water quality.

[0071] Figure 1 A schematic structural diagram of a filtering device according to an embodiment of the present application is shown. Figure 2 Show Figure 1 A magnified schematic diagram of region D in the middle. Figure 3 Show Figure 2 Schematic diagram of the cleaning device structure in the F direction. Fig.11 Show Figure 8 Cross-sectional view along CC direction.

[0072] The cleaning device 3 includes: a slider 31, which is sleeved on the circumferential outer wall of the limiting device 5; a positioning plate 32, one side of which is rotatably connected to the slider 31; and a circular hole 33, which is arranged on the surface of the positioning plate 32; a mounting ring 34, which is rotatably arranged in the circular hole 33 and is configured to be used for installing a scrubbing part 35, and the scrubbing part 35 is sleeved on the circumferential outer wall of the catalytic filter element 2. The limiting device 5 includes: a prism 51, both ends of which are respectively passed through the sealing plate 13 and the driving plate 12, and are rotatably connected to the sealing plate 13 and the driving plate 12; and a guide groove 52, which is arranged on the circumferential outer wall of the catalytic filter element 2 and is spirally arranged along the extension direction of the catalytic filter element 2; a guide rod 53, one end of which is connected to the inner wall of the mounting ring 34, and the other end is slidably arranged in the guide groove 52.

[0073] In use, since the catalytic filter element 2 is a spiral structure, the position of the slider 31 is always upward when the catalytic filter element 2 rotates. Therefore, when the catalytic filter element 2 rotates, the mounting ring 34 is driven to move along the extension direction of the surface of the catalytic filter element 2. At the same time, since the limiting device 5 is a prism 51, the slider 31 is driven by the mounting ring 34 and only moves back and forth along the vertical direction of one side of the prism 51, and does not rotate around the prism 51. Therefore, when the catalytic filter element 2 rotates, the mounting ring 34 can be moved on the surface of the catalytic filter element 2. The brushing part 35 installed in the mounting ring 34 is driven by the movement of the mounting ring 34 to brush the filter element, thereby achieving the purpose of automatic cleaning.

[0074] It is worth noting that, since the cross section of the prism 51 is a polygonal structure, when the driving plate 12 and the closing plate 13 need to rotate around the prism 51, it is only necessary to open circular grooves at both ends of the prism 51, and connect them with the mounting holes on the surfaces of the driving plate 12 and the closing plate 13 through the circular grooves;

[0075] It is worth mentioning that a guide groove 52 is provided on the circumferential outer wall of the catalytic filter element 2, and the guide groove 52 spirals along the outer wall of the catalytic filter element 2. When the catalytic filter element 2 rotates, the guide rod 53 slides in the guide groove 52, and at the same time, the guide rod 53 drives the mounting ring 34 to make a circular motion around the surface of the catalytic filter element 2, thereby driving the brushing part 35 to move on the surface of the catalytic filter element 2 while rotating around its surface, thereby improving the cleaning efficiency.

Figure 2 Show Figure 1 A magnified schematic diagram of region D in the middle. Figure 4 Show Figure 2 Schematic diagram of the cleaning device structure in the F direction. Figure 6 A schematic diagram of the structure of a sewage discharge plate according to an embodiment of the present application is shown. Figure 8 A schematic diagram of the three-dimensional structure of a sewage discharge plate according to an embodiment of the present application is shown. Fig.11 Show Figure 8 Cross-sectional view along CC direction.

[0077] The brushing part 35 includes a brush 351; a plurality of brushes 351 are provided, and the plurality of brushes 351 are arranged at intervals along the inner wall of the mounting ring 34; a drain plate 352 is provided with a first sliding hole 353 on the surface, and the first sliding hole 353 is used for sliding connection with the prism 51; and a second sliding hole 354 is also provided on the surface of the drain plate 352, and the second sliding hole 354 is arranged at an eccentric position on the surface of the drain plate 352, and the catalytic filter element 2 is slidably arranged in the second sliding hole 354, and the drain plate 352 is configured to drive the drain plate 352 to move on the surface of the prism 51 when the catalytic filter element 2 rotates around its own central axis; at least one limiting groove 355 is provided on the circumferential outer wall of the drain plate 352; a limiting track 356 is provided on the inner wall of the cylinder 11 along the axial direction of the cylinder 11, and is configured so that the limiting track 356 cooperates with the limiting groove 355 for the drain plate 352 to move along the inner wall of the cylinder 11.

[0078] In use, the top surface of the drain plate 352 is connected to the bottom surface of the slider 31. When the mounting ring 34 rotates and moves around the catalytic filter element 2, the drain plate 352 does not rotate when the catalytic filter element 2 rotates because the limiting grooves 355 on both sides are clamped on the surface of the limiting track 356. At this time, affected by the rotation of the catalytic filter element 2, the drain plate 352 rises or falls together with the slider 31. When the drain plate 352 moves, the sewage between the top surface of the drain plate 352 and the top surface of the cylinder 11 is squeezed, and the cleaning device 3 located above the drain plate 352 first cleans the surface of the catalytic filter element 2. The dirt on the surface of the catalytic filter element 2 is then scraped off by the second sliding hole 354 on the surface of the drain plate 352, and the sewage in the cylinder 11 is squeezed through the drain plate 352, so that the pressurized sewage rinses the filter holes on the surface of the catalytic filter element 2. Compared with the traditional brushing cleaning method, the cleaning efficiency is low, and the impurities that penetrate into the filter element cannot be removed, and manual cleaning using a high-pressure water gun or the like is required. The drain plate 352 structure provided in the present application can achieve the purpose of unblocking the filter holes of the filter element by pressurizing the sewage in the cylinder 11.

[0080] The driving device 4 includes: a gear ring 41 disposed on the bottom surface of the driving plate 12 ; a gear 42 meshing with the gear ring 41 ; and a driving motor 43 connected to the gear 42 .

[0081] During use, the driving device 4 drives the gear 42 to rotate through the driving motor 43, thereby driving the gear ring 41 meshing with it to rotate through the gear 42, and then realizing the function of driving the driving plate 12 to rotate on the inner wall of the bottom end of the cylinder 11 through the gear ring 41.
